LAMP BURNER.

SPECIFICATION forming part of Letters Patent No. 359,122, dated March 8,1887.

Application filed December 31, 1886. Serial No. 223,071. (No model.)Patented in England September 13, 1886. No. 11,595.

To all whom it may concern.-

Beitknown that I, FRANCIs ROBERT BAKER, a subject of the Queen of GreatBritain, residing at Arcade Chambers, Snow Hill, Birming ham,England,haveinvented Improvementsin the Raising and Lowering ofLamp-Galleries, (for which I have applied for Letters Patent in GreatBritain, dated September 13, 1886, and numbered 11,595,) of which thefollowing In is a specification. v

This invention relates to that class of lamps in which the gallery orglobe-holder is supported and carried by rods depending from the underside of the said holder, and which said rods slide freely withinvertical guideholes or tubes situated in the middle of the fixed burnerpart of the lamp and the object of my said invention is to facilitatethe raising and lowering of the said galleries or globeholders, for thetrimming of the wick or wicks, the refilling of the oil-reservoir,andthe ligl1ting of the lamp and my improvements consist, essentially, inthe provision of novel means for raising and lowering lamp galleries Iof the kind described.

Figure 1 represents in longitudinal vertical section a portion of a lampor a lamp-burner provided with improvements constructed according to myinventiomwith the gallery and 0 burner part represented in their loweredpositions. Fig. 2 represents the same with the cone or burner part andgallery raised from the wicks or burner-body for the lighting of thelamp,or for the trimming of the said wicks,

or the relilliug of theoil-reservoir through the body of the burner.Fig. 3 is a side elevation of a portion of the burner-body.

a is the body of the burner of the lamp, which is of the ordinaryconstruction, and b is the gallery, and c the cone combined with andmoving with the gallery, and upon the under side of which said galleryand cone a guide-rod, d, (upon one side,) is conducted and passesthrough the body of the lamp. The

other side of the lamp is provided with aloop, 6, having an eye, 6',sliding over a fixed condueting-rod,f.

g is a chain or flexible cord attached at its lower end to the guide orguide-rod (I, while the upper end of the said chain or flexible cord isattached to the short arm 71.2 of a lifter, h, which turns about a pinor center, 2', as a fulcrum, which is supported by a bracket, j. Thebearing If of the lifter is slightly elougated to admit of the lifterslightly rising and.

falling on the affixing of the gallery in its raised position, asrepresented in Fig.3. The extreme end of the said short arm h is madewith the shoulder h, which drops upon the edge a of the body of theburner a, thereby affixing the gallery in its raised position. k are thewick-tubes, through which the wicks Z pass.

To raise the gallery and burner b c, in order to gain access to thewick, depress the long end of the lifter h, when the chain or flexiblecord attached to the short arm pulls up the rod d and with it thegallery and cone, and when the said gallery is in its fully-raisedposition and the lifter liberated, the shoulder h of the short arm 71drops upon the top edge, a, of the burner-body, which thereby-holds thegallery in its raised position, the rising and falling being allowed forin consequence of the bearing being elongated.

To lower the gallery, pull outward the lifter, when the catch end isliberated by forcibly drawing the shoulder over the top edge of theburner, and when thus liberated the parts resume their normal positionsby gravity.

Having thus described ulyinvention, I claim as new and desire to secureby Letters Patent- 1. The combination, with the burner-body a andcombined gallery and burner c b, of the gallery lifting mechanismcomprising the chain 9, lever h, and movable guide-rod d, substantiallyas described.

2. The combination, with the burner-body a and combined burner andgalleryb c, of the guide-rod d, chain g,and lever h, provided with theelongated slot h", fulcrunrpin 1;, and shoulder h, substantially asdescribed.

Signed this 4th day of November, 1886.
